ticularly to that type of furnace known es und-erfeed Stoker. and hasvfor its object tlie pro-.visionjof such u furnace in which theulnnuntvof imconsumed combustible mute-k rialpassing out with the ash isreduced to a minimum.

A further object is to provide a furnace of thi,l typo in which theloro` of time duc to Vthe nccesity i'or clcunin; r of the furnace isreduced to :i minimum.

A still furthcrobjcrt is the provision ot' a furnace of this tnvpcl theparts ot' which are readilyY intel-chinigcahle and rhcnply constructed.f

Referring now more particularly to the drawings, the numeral l()indicates a boiler furnace as a whole. Mounted within the lireht'ix ofthe. furnace are retorts 11. Tin` front ends of these retorts are boltedor otherwise secured to the tire front and wall 10 of the furnace` andthe rc'ar ende of the retorts are held in position by a {'late Ii)arranged transversely of the fire ox, the ends. of this support beingwalled in the si valle ot' the furnace. und the lower edge r ing uponthe horizontal top ofso cross reali 13v which wall forms the fron Iendot' a water Sealed chamber hereinu -ter described. The plate 12 is4provided with recesses l2 adapted to receive the rear ends of theretorts 11. the top of the re` end of thc retort being' substantiallyflush 'with the lop of the support as is cleurly shown in Fig. 1.

BQ referring to Figs. 2, 4, 5, 6, 8 and 9 it will hc seen that thebottom 14 of theretort is lmrizontal throughout itgV entire length. andthat the to a ofthe retort slopes from front to back. The front of theretort is restricted. .as at 15` this restrictedjportion being'approxinmtely V-shaped, es Shown in Eig. D., the base oi the V spreading'rearwardtv to form an enlarged rear section 'nhiclr is approxinmtely-U-shnped, as shown Vin Fig; H. The tops of 4the Sides of the retort'(are turned at right :ingles forming shoulders 1l provided withhorizontal steps '11" as clearly Shown by Figs. 1, 2, 4 and 6, havin;ropenings ll' adapted to receive twyers 17. The steps 11b ofthe shoulders11n of the ret-orte are also provided on their upper Surfin-cs with lugs18 for a purpose hereinafter to be described.

Mounted against thc sidewalls of the fun nace und suitably secured attheir forward ends to the fire front and Wall as at 19* are beinginclined then the other of the cylinder.

side bars 19, the upper edge ofthe Side bars rearwardly at the sameangle as the upper ed 'es of the retort, and the rear ends of the sitebars resting upon'tlic transverse support 12. These side bars areprovided with steps 19l similar to the steps 11" of the retorts havingon their upper Vsurfaces spaced lugs 20- corresponding in number andarrangement with the lugs 18 formed upon the retort. Spanning the spacebetween the retort and the side wall are plates 21 suitably reinforcedon their under sides,` as at 22 and provided with notches 23 adaptedttoreceive the lugs 1S of the retort'and lu 20' of the side 'supports, theends of t e plates resting upon the steps of the sliouldersof the retortand the upper surface. of the side bars. These plates are so arranged asto form a continnous,` rearwardly inclined latt'orm, as is clearly shownin Figs. 1 an 2.

Similar plates 21 are provided intermediete the retorts'. It will thusbe seen that the spaces between the side walls and the retorts andbetween the retorts themselves are provided withia continuous rearwardlyinclined platform.

Means for feeding fuel to the furnace is shown as comprising a pressurecylinder 24, having mounted therein n piston 25 and provided with theusual means for governing.

the flow 0f the Huid into first one end and This piston 25 is providedwith a piston .rod 26, to thil outer end of which is secured a ram head27. This rain head works in conjunction with the usual hopper H to feedfuel from thtl hopper into the mouth of the retort.

Arranged within the forward end of thc retort 11 is an angularlydisposed dcliectingr plate 28, the ur ose of which is to prevent pilingup of t `e ucl at the front wall of the firebox. Means to insure againstpackin, r or wedging of the fuel under the delqcting plate 28 isprovided, comprising a `brcakinpr bar 29, which operates alongftheinterior of the horizontal bottom of the retort and rear end of ram ease27". This breaking har is secured to the rain, as at 30, and thereforehas the same stroke as the ram. lpo'n its upper surface and adjacent thehead ot the rain, the breaking bar is providedwith lugs 31 which gripthe' fuel and causo it to. shift.

The rear end of the breakingr bar is provided with a wedge portionBzavhich aills in the rearward movement of thc fuel bedand ashes. t

lt will be seen that between tht,l front wall and the support 12 thebase oithc l'irc box and the plates 2l what ils in ctfcct a closed spaceis formed. luto this space is introduced a forced draft by anv suitableuic-ans as at l). the draft passim;r through the opcn bottoms 17 of thctwyers 17 and out through 6a the openings 17b thereof.

ber 33, in which are longitudinally arranged ash supports 34. Thesesupports comprise cylindrical members 35 rovided with a longitudinalopening 36. ign the present illustration I have shown these cylindricalmembers as beingr sup orted by disks 37 mounted u on shafts 38, t e endsof which are provided with sleeve disks 38 mounted in suitable beuringsin the side Walls of the chamber, the tubular members being bolted orotherwise suitably secured to the disks. Means for rotating these disksis provided, comprising` a lever 39, having mounted there on 'a pivoted,weight-operated pawl 40, engaging a ratchet gearifil suitably secured toone of the tubular members. this tubular member being transmitted to theother two tubular members through the mediuni of a gear 42 suitablysecured to the The motion of `gears 43 and 44 secured to the remainingtubular members. It will be seen that when the lever 39 is oscillatedinan manner, as by means of a rod 45, operate(l by hand or power asdesired, the tubular ymembers are rotated. ln order that the powerrequired to operate the rotary members may be reduced to a minimum, theopenings in the tubular members are so arranged that but one is inoperatingr position at a time.

The operation of my device is as follows:

Fuel being forced intti the retort periodiv cally or continuously as maybe required b v the pressure actuatcd ram 27, moves smultancouslyupwardly and rearwardly from the impulso received by the ram andl'peakerbarili), raising` to thc top of the level ot' the retort, piling up atthe forward end of theretort being prevented b v a dcflcctor platt- 28.lloro thc air ncccssaryY to combustion is z )plied by the twycrs 1T, andbecause of thc peculiar construction of thc. rctort thesc twycrs arcconstantly supplying air to fresh fuel.y Duc to the tendency of thc fuelto 'like up, thc furl after leaving;- thc dcicctor plate 28 willovcrliouand fall upon the plates 21. but does not become stagnant onthcsc plates as tlul dragging eiicct ot thtl moving edges of thc mainbody of fucl in *hc retort will have a tcndclicy to carry this ovorHowdownwardlyv and rearwardly". dt will rcadlv hc secu lrjv ih oscfamilial' with tho "rt that by properly adjusting'lhc flu-l l'ccd. thct'lul arriving at thc hrwrr rearward cud of thc retort will bc utmostil' 'not entirely con sumcd. 'l`o prevent tho loss` of :in v unconsnlncdfucl which may pass over thc rear end of tu rctort` the rotar)v tubularnicmbcrs licreiul'icfore "dcscribml havc Iwcn providcil 'l`hcsc membersrcccivc thc falling ash and unconsunlcd.particles and support thcm. thcunconsumcd particlcs bring provided with air for combustion through thccheckers nausea through o )enings C orfrom elsewhere. It will be unerstood that the opening t" of the checkers are but slightly above thelevel of 'the openings thereof into `constant engagement with the.bottom of they ac'euniulating lr ashes for removal therefrom. To preventthe heart generated by the combustion laboi'e the tubular members fromburning the members out and thus destroying them, they are partially orentirely submerged in water and are thus cooled as they are rotated.

It will be obvious to those familiar with the art that many changes ofconstruction as regards size and shape of the particular elements may be)mide without departing in .my sense from the. spirit of 'the invention,and I accordingly do not limit myself to the specific structure hereinshown and described.
